Abstract
Procedimiento para la electrolisis de soluciones acuosas de halogenuros de metales alcalinos en celdas de membrana con valores de pH superiores a 1,0 en el recinto anódico, conduciéndose la solución de halogenuro de metal alcalino a través del recinto anódico así como de zonas para la concentración con halogenuro de metal alcalino y para el ajuste de valor de pH, caracterizado porque se ajusta por lo menos una corriente parcial de la solución concentrada a temperatura elevada a un valor de pH inferior a 1,0 y después de ello se la eleva a un valor de pH en el margen de 1,0 hasta 6,0.
